To all whom it may concern:

Be it known that I, DAwsoN W. Dunna'r'r, a citizen of the United States,and a resident of Clarksville., county of Montgomery, State ofTennessee, have invented certain new and useful Improvements inGrain-Scourers, of which the following is a full and clearspeciiication, reference being had to the accompanying drawings, inwhich- Figure 1 is a vertical longitudinal sectional view of a machineembodyin the essential features of my invention; ig. 2 a side elevationin detail of the automatic moistener; and Fig. 3 a detail perspectiveview of the automatic scouring or peeling devices, the parts beingseparated for the purpose of better illustration.

rlhe object of this invention is to provide a simply constructedapparatus for automatically` moistening and scouring or peelmg grain,and the invention consists of certam .novel Jfeatures of constructionhereinafter described and claimed. In the drawing a designates a spoutor hopper adapted to conduct the grain into one end of the top conveyertube rThe ther or tail end of the tube h discharges i into an inclinedtube c which in turn dist charges into a second eonveyer tube ci ar- 30ranged belowtube lb, The other end of the tube a? discharges by means'of an inclined tube c into the forward end of still another conveyertube and the tail end of this latter tube discharges into a spout 'gfrom ducted to a suitable A rotary conve er in each one of the Iconveyer tubes i: es to forcibly move the v i' in along .the same, thesescrew conveyers 40 eing driven .in the direction of the arrows anysuitable mechanism. ln-the spout a isa depending valve plate i whoseshaft is` l extended throuh the side w of the spout and is wei hte atjto cause the valve to normallyy oseu Attached tc-one end of the shaft ofthis valve' .is an armjc, the free end orf-this arm being connected by`means of a linka? te a sliding'rod m, the outer end cf this ,rodlmcarrying a funnel shaped tube n.

A water tank 0 supplies water to this funnel through.v a suitable valvedpipieg p.

- The funnel is ada ted to charge either into a passage g'lea ing intothe upper conveyer tube or into the inletend cfa waste e r. When nograin is passie through the spout the valve plate i 1s held c osed andvi A Specication of Letters Patent. Application led March 11,- 1912.Serial, No. 688,009;

with a waste pipe 1' so that the water which drips from the water supplymeans will run olf into the waste pipe; but as soon as the grain beginsto flow down through the spout the valve plate will be shifted, theweight j will be raised and the funnel will be pushed back until itsoutlet is coincident with the passage g, so that thereafter the waterwill be discharged into the upper conveyer tube. ln this'way I provide asimple automatic mechanism which will cut off the supply of water assoon as the supply oi grain to the upper conveyer ceases, therebyavoiding the necessity of manually cutting olf the water every timethere is an. intermission in the supply of grain.

, is construction is advantageousl for the further reason that it avoidsthe use of means for automatically opening and closing the valve in thesupply pipe'p, 1t being simp'ly necessary to roperly adjust the valve atvthe `beginning o the operation'o the machine, and thereafter the feedwill be uniform. sight-feed for the water since at all times thedropping of the water from the end of pipe p may be observed.

ln the tail or discharge end of each Vof the conveyer -tubes is lmounteda metal open ended tube s into which the end of the conveyer extends.The outer or discharge end of this tube s 's normally closed by a disk twhich may be constructed of some rigid material as metal or of someexible or yielding rllhis construction also provides a the funnel isnormally in communication material such as stiff leather or rubber.

This disk fits squarely against the outlet end of thetube and normallycompletely closes the same, it being pressed to its seat on the end ofthe tube by a coil sprin u whose outer end bears against a pressure ar vsuported on rods fw, suitable thumb screws w Being threaded von the endsof the rods for the purpose of varying the action of the s rin on thedisk. With a construction of t is c aracter it will be observed that theAscrew conveyerwill forcibly ress the grain against the disk and this w'll result in the disk moving away from the end of the tube far enough topermit discharge 'of the gram. The grain will be forcibly pressed outand the friction between the `face of the disk and the annular edge ofthe tube a will be sufcient to clean and scour or peel the grain, thepressure being regulated to suit the exigencies of the case and thenumber of conveyer veyer tube and employing the shaft of the conveyertoassist 1n supporting the adjustmg means, it will be seenvthat I providemeans whereby the attendant may readily have access at all times to theparts in order that the pressure of the disks may be nicely regulated. f

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is- 4 l. A grain scourer consisting of aconveyer tube, a screw conveyer therein yhaving its shaft extendingbeyond the end of said tube, a scouring disk adapted to close the end ofsaid tube and being mounted slidably on the extended end of the conveyershaft, a

spring on the extended end of the conveyer shaft, and means mounted onthe conveyer tube and said shaft for varying the pressure ofsaid springon said disk.

2. A grain scouring means consisting of a conveyer tube, a screwconveyer therein having its shaft extending beyond the end of the tube,a scouring dis adapted to close the end of the tube and mounted on theconveyer shai't9 a pressure bar slidably mounted on said shaft, a springbetween said pressure bar and the disk, and adjusting means for thepressure bar supported on the conveyer tube, for the purposes set forth.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
